Examaple 4 Find the values of x, y and z so that the vectors ๐ โ = x๐ ฬ + 2๐ ฬ + z๐ ฬ and ๐ โ = 2๐ ฬ + y๐ ฬ + ๐ ฬ are equal. ๐ โ = x๐ ฬ + 2๐ ฬ + ๐ง๐ ฬ ๐ โ = 2๐ ฬ + y๐ ฬ + ๐ ฬ Since ๐ โ = ๐ โ Comparing corresponding components, Thus, x = 2 , y = 2 & z = 1 ๐ โ = x๐ ฬ + 2๐ ฬ + ๐ง๐ ฬ ๐ โ = 2๐ ฬ + y๐ ฬ + ๐ ฬ Since ๐ โ = ๐ โ Comparing corresponding components, Thus, x = 2 , y = 2 & z = 1
